Poblano Duck with Charred Corn Polenta
I have fallen in love… with a chili. A poblano chili, to be specific. Two weeks ago I dined at Birch and Barley on 14th Street in DC, and tried a bite of the grouper and I was intrigued by the flavor tucked underneath the flaky fish. I was blown away by the pure flavor from the beautifully green poblano puree at the base of the plate. I had enjoyed poblanos previously only in chili rellenos… so filled with gooey cheese and fried in an eggy batter. But I had never tried it in its own puree. I had to replicate it somehow, but make the dish my own.
A few days later, the dish started to develop. I decided on a poblano tequila puree, cuz why the hell not throw some tequila in there? Then I realized the chili may be too spicy, so lets cut it down… what is fresh and in season? Peaches! Then I wanted to bring in a rich protein, so duck was a natural, that I would marinade in a citrus blend of fresh orange and lime. Finally, I wanted a little smokiness to the dish with some contrasting color… so I decided on a charred corn polenta with toasted pine nuts. The idea was created, and it was time to see how it would turn out.
Ingredients
Duck
2 duck breasts, skin on
3 oranges
3 limes
3 ancho chilies (dried poblanos)
4 cardamom pods
Puree
4 poblano chilies
1 peach
2 oz anejo tequila
1/2 lemon
Charred Corn Polenta
2 cups polenta, or corn grits
4 cups water
4 cups heavy cream
1-1.5 stick unsalted butter
3 ears of corn
1/3 cup pine nuts
Salt for flavor
Preparation
1) Generously salt duck breasts on both sides, and marinate in the juices and rinds of limes and oranges. Dice ancho chilies and add to the marinade. Smash cardamom pods and add to marinade. Store in refrigerator… the longer the better (I marinated for 6ish hours).
2) Char poblano chilies until cooked and outer layer completely blackened. I do not have a grill that gets hot enough to do this (I HATE the electric grill at our building!! (first world problems)). So I put down a little tinfoil on our gas range, and did it on the stove! Peel outer charred layer, removing all black char… this is important to get the great green color you are looking for. Peel skin from peach, and cook in a dollop of melted butter. Add tequila and cook off alcohol. BEWARE: your pan will catch fire, but that is just the alcohol burning off… chill out. The last thing you want is fire extinguisher chemicals in your puree. Combine chilies, peach/butter/tequila, and juice from half lemon into food processor and puree thoroughly.
3) Char the corn, similar to poblano chilies, until cooked thoroughly. Mine were pretty much burnt, but frickin delicious. Cut from the cob, and set aside for later.
4) Remove duck breasts from marinade, and place in a lightly buttered skillet on low/medium-low, with the skin side down. The trick here, as advised by my friend and duck hook up Jason at Cork Market, is low and slow. So you want to cook it until the duck fat renders and you get a nice golden crispy layer of duck skin (aka fat), 12-17 minutes. After you get that golden crisp, flip the duck and increase the heat to a medium and cook until you get a nice sear, about 5-7 minutes. Remove from heat, and let sit for a few minutes.
5) In a small pot, take the remaining citrus rinds, juices, cardamom pods, and chilis and fill with water. Bring to boil and simmer while the duck is cooking. This can be drained and used later to drizzle over the duck for additional flavor.
6) While the duck is rendering, bring liquid polenta ingredients to a boil in a medium pot. Add polenta and a stick of butter, reduce heat a bit and stir continuously. Toast pine nuts and add to pot. Once you get the consistency you want (more firm for polenta, more runny for grits), add corn and pine nuts, and remove from heat.
7) Plate and enjoy!
